Usually its users discover sooner or later that their program does not deliver all the desired results, or worse, that the results requested were not the ones really needed.

Clearly, programming courses should teach methods of design and construction, and the selected examples should be such that a gradual development can be nicely demonstrated.

Software gets slower faster than hardware gets faster. (Or, sometimes known by] Grove [the head of Intel] giveth and Gates [the head of Microsoft] taketh away.)

Usually its users discover sooner or later that their program does not deliver all the desired results, or worse, that the results requested were not the ones really needed.

In the practical world of computing, it is rather uncommon that a program, once it performs correctly and satisfactorily, remains unchanged forever.

Prolific programmers contribute to certain disaster.

Good engineering is characterized by gradual, stepwise refinement of products that yields increased performance under given constraints and with given resources.
